g0n, 1180, who represents (Pi,, vi. and vn.) an Apiocrhiites from the Canton 

 of Solothuru. This figure corresponds with HOFER, and suggests to me, that 

 the specimens from Swisserland are, if not a distinct species, at least a variety 

 of ApioiTinites rotundus. The thickness of the first costae, and less pear- 

 shaped form, appear to be characteristic. Should it prove a new species, I 

 propose for its name Apiocrinites elongatus. In the tabular arrangement of 

 the Crinoidea it will follow A. rotundus, rendering a further subdivision 

 necessary.
